Development and service of drilling fluid

The interval 2816-4705 m was drilled with the utilization of polymer-inhibited drilling mud PIBR-2M. Casing setting and cementing were made by two sections. Cementing jobs were successful. Now we are preparing to replace the flushing liquid, as further drilling of the well will be carried out on a clayless drilling fluid Biocar. The entire volume of drilling mud was prepared on the surface.
